All you really need is the ability to (kind of) talk and breathe.
So, at which level should you be exercising?
Try doing level three workouts twice a week, level two workouts twice a week, and a level one workout once a week if you want to have a well-rounded fitness routine, says Burgau. But it really does depend on your fitness goals and workout experience.
“If you’re new to working out, you might have to build up to a point of reaching a level three intensity,” says Burgau, adding that it’s also important to listen to your body.
“Your body will tell you if you’re overdoing it and when rest is required,” he says. “Training fatigue is a serious sign of overtraining. If your workouts are leading to decreased force production and emotional or sleep disturbances, it’s time to scale back. It’s important to understand that everyone responds differently to exercise, especially vigorous exercise.”
